IMPROVEMENT IN MACHINES ECR MAKING CARPET-LININGS.

i Specification forming part of Letters Patent No. 157,852, datedDecember 15, 1874; application tiled November 20, 1874. I

To all whom it may concern Be it known that I, THOMAS J. MAYALL, ofBoston, Suffolk county, and State of Massachusetts, have inventedcertain new and useful Improvements in Machinery for Making Garpet-Lining, of which the following is a specification:

The object of my invention is to manufacture, in a speedy and economicalway, carpetlining composed of flattened paper tubes provided with alling of cotton, batting, or lap, or other suitable material, said tubesbeing placed parallel with one another, and united by strips or tapesextending crosswise of the tubes.

The carpet-lining itself is not here claimed, but is made the subject ofa distinct application for Letters Patent.

My lpresent invention relates to mechanism for making one variety ofthis lining, in which the flattened tubes extend crosswise of the lengthof the completed lining, and are united by longitudinal strips or tapes.To this end I employ endless aprons and pressure-rolls, which serve tocarry along the iiattcned tubes and to press together the same and thebinding-tapes, in combination with tape-rolls that deliver the tapes orbinding strips between the two aprons, and above and below the flattenedtubes, and a pasting, gumming, or cementing mechanism, by which saidtapes, before coming in contact with the tubes, are coated with paste orsome adhesive material that, when the vtapes are pressed upon the tubesby the action of the apron or pressurerolls, will cause the said tapesand tubes to be rmly united together. Y

The accompanying drawing represents the mannerin which my invention isor may be carried into effect.

Figure l is a side elevation of the machine. Fig. 2 is a longitudinalvertical section, Fig. 3 a plan, and Fig. 4 an end elevation, of thesame.

The various parts of the machine are supported in a frame, A, of anysuitable structure and formation. The flattened tubes shown at a are fedto the machine preferably from a feed-table, B, provided with a suitableadjustableA gage, b. This feed-table meets the lower horizontaltraveling-apron C, which is an endless band passing around end drums CIC2, the latter of which has its bearings in boxes c, adjustable by meansof set-screws c', so as to maintain the apron at the proper tension.Above the lower apron, and beginning at a point preferably in advance ofthe feed-table, is a second apron, D, traveling around drums D1 D2. Thetwo aprons travel in contact with one another, and their drums C2 D2 actas pressure-rollers. Under the drum D1 is another drum, O3, locatedbelow the upper face of the lower apron, and this drum and the upperdrum D1 act also as pressure-rollers. The journals of drum D2 aremounted in bearings, adjustable like those of the drum G2, and for thesame purpose. The aprons on their eXterior faces have a series oftransverse ribs or bars, d, which are spaced so that the distance fromone to the next shall about equal the width of the flattened tube. Theribs or bars on the upper and lower aprons register or come together, sothat when the tubes and tapes pass into the machine, the upper and lowerribs will come together upon those parts of the tapes interveningbetween the ilattened tubes. The tape-rolls are shown at E for the uppertape-rolls, and F for the lower taperolls. as it is desired there shallbe longitudinal binding-strips. Three rolls are shown in the drawing.The rolls of each set are represented as mounted on a single shaft; butin practice I prefer to mount each roll on a separate axis or bearin gstud, from which it may be removed and replaced by a new one withoutinterference with the others. The tapes pass over cylinders G, whichrevolve in troughs H containing paste or other adhesive material. Thecylinders are, of course, provided with doctors to remove surplus paste.The lower tapes c pass up over the cylinderG and around a roller, I,whence they pass under the feedtable to and just above the lowerfeed-apron, as indicated in Fig. 2. The upper tapes f pass from theirpaste-cylinder G to and under the drum D1. The various drums of theaprons may be geared or belted together, so as'to revolve in unison.

The operation of the machine is fully shown in Fig. 2. The flattenedtubes, which are fed one after the other from the feed-tables onto Theremay be as many rolls in each set the lower' traveling-apron, rest on thelower tapes e, and when they reach the rolls or drums D1 G3 they meetthe upper tapes f, and by the action of said rolls, the tapes arepressed upon the flattened tubes, and the whole are caused to adheretogether. The tubes lie in the spaces between the ribs on the apron, andsaid ribs on the upper and lower aprons come together, so as to compressand stick together those portions of the tapes intervening between thetubes.

Between the two sets of pressure drums or rolls are arranged steam-pipesH above and below the carpet-lining, so that the latter, by the time itemerges from the machine, may be thoroughly dried and completed. Thisfeature is desirable, because it both facilitates the work and preventsliability of the tapes getting loose from the tubes.

I have used the word tape-rolls to distinguish the rolls that carry thebinding-strips; but it will be understood that the bindingstrips may benot only tape, but any other suitable material, such, forinstance, aspaper.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-

feed-table, and the tape-rolls, and pasting de- THOS. J. MAYALL.
